universal filament spool holder

A remix of dbardini's remix of yoyoek1's filament spool holder. :D

I just added a wedge and lip to the bearing attachment pin, for those of us who haven't dialed our printer in to be atomic precise.

print 2 of the spacers "arm" and 2 of the bases "wedge".

You will also need 4x 608 ball bearings. (same kind as in most rollerblades and skateboards... and fidget spinners)
